Key result

Temp.:

20°C

Parameter:

dynamic viscosity (in mPa s)

Value:

15.352

Key result

Temp.:

40°C

Parameter:

dynamic viscosity (in mPa s)

Value:

5.968

Conclusions:

Using a rolling ball viscosimeter, viscosities of

15.352 ± 0.001 mPa * s at 20.00 ± 0.02 °C
and
5.968 ± 0.019 mPa * s at 40.00 ± 0.00 °C

were measured.

Executive summary:

The viscosity of 3-Methylpyrazolwas determined according to OECD guideline 114 as 15.352 ± 0.001 mPa * s at 20.00 ± 0.02  C and as 5.968 ± 0.019 mPa * s at 40.00 ±0.00 C. Both values are the means of two triplicate determinations ± standard deviation for each temperature. As the measured RSDs were 0.01 % for the determination at 20 °C and 0.32% for the determination at 40 °C, the validity criterion for ball no. 2 is met for both determinations. Measurements were performed at 20.00±0.02 °C respectively 40.00 ± 0.00 °C.
